Title: Improvements in or relating to the production and use of coloured printing compositions, and the compositions thus produced
IPC: C09B63/00
Filed: 1936-01-02
Abstract: In the preparation of a printing composition by separately dissolving in an organic solvent a dye and a lake-forming precipitant therefor, the solvent used is a water-miscible but substantially water-free glycol ether.  A water-insoluble thickener, such as nitrocellulose, or a water-soluble thickener, such as methylcellulose, may be incorporated.  A basic dye may be used with a heteropoly mineral acid, e.g. a phosphotungstic or phosphomolybdic acid, as precipitant. Specified glycol ethers are the monoethyl and mono-n-butyl ethers of diethylene glycol.  Acid impurities in the precipitant may be neutralized by introducing diphenylamine or sodium acetate.  In examples: (1) a composition made up from Rhodamine 6G, phosphatododecatungstic acid, diethylene glycol monoethyl ether and suitably thickened with nitrocellulose is applied to the entire surface or to selected areas of a fabric by printing, stencilling, brushing or hand painting and the fabric is immersed in, or otherwise wetted with, water to precipitate the pigment in the fibres; (2) a composition made up from Rhodamine 6G, phosphatododecatungstic acid and a mixture of the monoethyl (1 part) and monobutyl (3 parts) ethers of diethylene glycol and suitably thickened with nitrocellulose is printed on paper or other material and the printed material is brought into contact with water to precipitate the pigment thereon.  Reference has been directed by the Comptroller to Specification 275,969, [Class 2 (iii)].

Abstract: A process for the preparation of 1,8-di-isocyanato - p - menthane of the formula <FORM:0739820/IV (b)/1> comprises heating, at a temperature at least as high as its boiling point, a carbamate of the formula <FORM:0739820/IV (b)/2> in which R1 represents a monovalent hydrocarbon group free of non-benzenoid unsaturation, in the presence of a basic catalyst consisting of (a) water-soluble metallic compounds of such basic strength that their 0.1 N aqueous solutions have a pH of at least 8, preferably from 10 to 13 at 25 DEG  C.; or (b) water-insoluble basic metallic compounds which are capable of neutralizing a strong mineral acid such as sulphuric or hydrochloric acid and isolating said 1,8-di-isocyanato-p-menthane by distillation from the mixture of said carbamate and said basic compound.  The group R1 may be e.g. an aliphatic group such as methyl or ethyl, an alicyclic group such as cyclohexyl or an aromatic group such as benzyl.  Basic catalysts mentioned include the oxides, hydroxides and alkoxides of alkali metals, sodium methoxide lithium oxide and potassium ethoxides, salts of alkali metals and weak acids especially of aliphatic carboxylic acids, e.g. sodium acetate, potassium carbonate and lithium bicarbonate. Alkali metals may be used.  Oxides and hydroxides of the alkaline earth metals, e.g. lime, barium hydroxide and strontium hydroxide, oxides and hydroxides of calcium, zinc, magnesium barium, strontium, cadmium, lead, mercury, manganese, iron, nickel, cobalt, cerium, copper and tin may be used.  Preferably the carbamate and the basic catalyst are heated to boiling with distillation of the products and the use of reduced pressure is recommended.  In the example 1,8-di-isocyanato-p-menthane is obtained by heating the diethyl dicarbamate with lime at reduced pressure with distillation firstly of ethanol at reduced pressure and secondly of the desired product which is purified by extraction and fractionation.

Patent HK-90590-A (HK)
Title: Computer-controlled cordless telephone
Inventor: BECKER WILLIAM RICHARD
IPC: H04W52/02
Filed: 1990-11-01
Abstract: A computer-controlled cordless telephone system having a base unit and a handset unit provides for increased functionality in communications between the base unit and the handset unit, and also provides a controlled power-up/power-down mode of operation for the handset unit. Increased functionality is achieved by employing a message format for control signals transmitted between the base unit and the handset unit in the form of frequency shift keyed (FSK) signals which include a data field. This data field may be in the form of either opcode data or digit data, thereby allowing for many different commands or functions. Power to a computer, a receiver and certain other selected circuitry in the handset unit is controlled to minimize power consumption when the handset unit is in an out-of-cradle-and-standby state. Power to other nonessential circuitry in the handset unit is turned completely off during this state. The handset unit automatically turns on to a full operating mode from the alternating power-up/power-down mode in response to events such as (1) a user depressing a key no the keypad of the handset unit for either initiating a telephone calls or paging the base unit, and (2) the base unit detecting an incoming ringing signal on the telephone lines.
